Problems With an Air Conditioning Circuit BreakerAir Conditioning Question:
My central Air Conditioning unit was not cutting off even when the temp was reached. The compressor would shut off but not the unit in the basement, even when I switched it off at the thermostat. So I manually switched off the power switch on unit. I left it off for about 40 minutes, when I switched it back on, the unit came on, but now it keep tripping the breaker after about 20 seconds. I don’t know if burner on the furnace is trying to re-start and won’t so that whats tripping it. Can I lock out the burner, start the furnace again a run the air conditioning without the burner until I can get a service tech out.?
Its an Oneida-Royal Furnace.

Thanks for your electrical question WGM.
Do not defeat any safety or limit switches. It does sound like a limit switch has failed or a component in the control circuit. Advise calling a qualified air conditioning technician to identify and repair the problem. In the mean time I would not run the unit if it is tripping the circuit breaker off to avoid damage to the unit.
